JANUARY 2009 This is an updated LZMA library wrapper provided with SDK 4.63. The SDK is available here: http://www.7-zip.org/sdk.html. It is written completely in C and compilation and integration is much simpler. To enable multithreading support, compile with COMPRESS_MF_MT and _REENTRANT defined. MF=Match Finder, MT=Multi Thread. In addition, link in pthread. This is default behavior in lrzip. For single thread support, remove these defines in the Makefile. Some additional documentation is provided from the SDK. File ./C/7zCrcT8.c is added to support ASM CRC code. Taken from p7zip.org. Original README text follows. This is a zlib like library for the lzma encoder/decoder originally created by Oleg I. Vdovikin and modified for lrzip by Con Kolivas It is based on a stripped down source tree of the lzma SDK by Igor Pavlov. http://www.7-zip.org You can build a standalone library called liblzma.a which gives functions equivalent to compress2() and uncompress() called lzma_compress() and lzma_uncompress(). Updated for recent SDK 4.57 and added assembler routines for crc using p7zip.org variant by Peter Hyman
